Water is boiled at sea level in a coffeemaker equipped with an immersion-type electric heating element. The coffee maker contains 1 L of water when full. Once boiling starts, it is observed that half of the water in the coffeemaker evaporates in 18 min. Determine the power rating of the electric heating element immersed in water. Also, determine how long it will take for this heater to raise the temperature of 1 L of cold water from 18°C to the boiling temperature. The enthalpy of vaporization of water at the saturation temperature of 100ºC iss hfg = 2256.4 kJ/kg. At an average temperature of (100 + 18)/2 = 59ºC, the specific heat of water is c = 4.18 kJ/kg·ºC and the density is about 1 kg/L.
